SI: Power Rankings25Toronto Raptors (12-26)The Raptors rank 29th in points per possession because many of the scorers trying to fill the void caused by Andrea Bargnani's absence are explosive but unreliable. Jerryd Bayless is a quintessential feast-or-famine player; he had 30 points against Washington last month, went 0-for-6 in 25 minutes against Golden State on Sunday and erupted for 12 points, six rebounds and three assists in the fourth quarter alone against Orlando on Monday. Linas Kleiza had consecutive games of five, 25 and two points, playing more than 20 minutes in each, in late January. Jose Calderon had a five-game stretch in which he averaged 21 points and never scored fewer than 14, but he has followed that up with a six-game period in which he's averaged 7.5 points and never scored more than 12. You know a team is in trouble when the most reliable sources of offense are Leandro Barbosa (shooting 43.3 percent) and DeMar DeRozan (41.3).
